In lottery analysis we usually count how often each number appears in past draws. High-frequency numbers are called “hot” and low-frequency ones “cold”. However, because draws are random, hot numbers will not necessarily keep appearing often, nor will cold numbers necessarily stay infrequent.
Consecutive numbers means two or more adjacent digits among the drawn numbers. By analysing historical data we can count how often they occur. Note, though, that every draw is an independent event and historical data cannot guarantee future results.
Split the number pool into zones (e.g. low, middle, high) and count how drawn numbers spread across them. This helps you understand how dispersed the numbers are — for data reference and entertainment only.
